Freelancer profile translated to English.

Description

Product-oriented Fullstack Developer, I have been working on business applications and critical web journeys for over 7 years. My core expertise lies in Vue.js/Nuxt.js, TypeScript, Node.js, and GraphQL, with a strong focus on architecture, quality, and user experience.

AI is an integral part of my daily work: I use it to explore codebases, prototype, document, and test, but also to design enterprise AI agents. Notably, I developed a conversational agent integrated with Slack, combining LLMs, business tools, deterministic workflows, human validation, evaluation, and observability.

I thrive in environments where developers participate in product decisions, collaborate closely with business teams, and transform complex problems into simple, reliable solutions.

I am primarily seeking a long-term freelance mission, while remaining open to a permanent position if the project and team are a good fit. Based in Nancy, I prefer remote work with possible presence in Paris (TGV line, 1h40) up to two days a week.
